Perception of microstimulation frequency in human somatosensory cortex
eLife, 2021 Microstimulation in the somatosensory cortex can evoke artificial tactile percepts and can be incorporated into bidirectional brain–computer interfaces (BCIs) to restore function after injury or disease.

Restoring the encoding properties of a stochastic neuron model by an exogenous noise [PDF]
, 2015 Here we evaluate the possibility of improving the encoding properties of an impaired neuronal system by superimposing an exogenous noise to an external electric stimulation signal. The approach is based on the use of mathematical neuron models consisting

Utility and lower limits of frequency detection in surface electrode stimulation for somatosensory brain-computer interface in humans [PDF]
, 2020 Objective: Stimulation of the primary somatosensory cortex (S1) has been successful in evoking artificial somatosensation in both humans and animals, but much is unknown about the optimal stimulation parameters needed to generate robust percepts of ...

Monosynaptic pathway from rat vibrissa motor cortex to facial motor neurons revealed by lentivirus-based axonal tracing [PDF]
, 2005 The mammalian motor cortex typically innervates motor neurons indirectly via oligosynaptic pathways. However, evolution of skilled digit movements in humans, apes, and some monkey species is associated with the emergence of abundant monosynaptic cortical

Microelectrode array recordings from the ventral roots in chronically implanted cats [PDF]
, 2014 ventral spinal roots contain the axons of spinal motoneurons and provide the only location in the peripheral nervous system where recorded neural activity can be assured to be motor rather than sensory.

Intracortical Microstimulation Elicits Human Fingertip Sensations [PDF]
, 2020 The restoration of cutaneous sensation to fingers and fingertips is critical to achieving dexterous prosthesis control for individuals with sensorimotor dysfunction. However, localized and reproducible fingertip sensations in humans have not been reported via intracortical microstimulation (ICMS) in humans.

Biomimetic rehabilitation engineering: the importance of somatosensory feedback for brain-machine interfaces. [PDF]
, 2016 Brain-machine interfaces (BMIs) re-establish communication channels between the nervous system and an external device. The use of BMI technology has generated significant developments in rehabilitative medicine, promising new ways to restore lost sensory-

In vivo measurements with robust silicon-based multielectrode arrays with extreme shaft lengths [PDF]
, 2013 In this paper, manufacturing and in vivo testing of extreme-long Si-based neural microelectrode arrays are presented. Probes with different shaft lengths (15–70 mm) are formed by deep reactive ion etching and have been equipped with platinum electrodes ...
